An anonymous reader writes "A 2011 ProPublica series found that the TSA had glossed over the small cancer risk posed by its X-ray body scanners at airports across the country. While countries in Europe have long prohibited the scanners, the TSA is just now getting around to studying the health effects." I'm not worried; the posters and recorded announcements at the airport say these scanners raise no health concerns.

SternisheFan writes with this news from the Register: "Apple has failed in its attempt to obtain a permanent ban on several Samsung products in the U.S., but Samsung's accusations of jury misconduct have also been rejected. As she has so many times before, Judge Lucy Koh kept things even between Apple and Samsung by rejecting most of their requests. After Apple won $1bn in its patent infringement case against the Korean firm, it set about pursuing another win in the form of permanent injunctions on the products in the case. The fruity firm wanted a California court to stop sales of the Sammy mobile phones and tablets in the U.S., but the judge said the company hadn't done enough to legally support such a ban."

GovTechGuy writes "Rep. Zoe Lofgren sat down with Roll Call to discuss her proposal to slow down the seizure of domain names accused of piracy by the federal government. Lofgren turned to Reddit for help formulating the bill, and also discussed whether her colleagues in Congress know enough about technology to make informed decisions on tech policy."

SchrodingerZ writes "After their yearlong mission to map the Moon's gravitational field, twin probes Ebb and Flow crashed into the lunar surface, ending the GRAIL mission. The crashes were controlled events, each impacting 30 seconds apart from each other. The twin spacecraft were running low on maneuvering fuel and NASA, not wanting the craft to fall on historical sites such as the Apollo landing sites, redirected their flight patterns to impart the far (dark) side of the moon. Their impact sites were named after Sally Ride, the first American woman in space. 'During the news conference last week, Maria T. Zuber, the principal investigator, said the probes would be crashing into a "non-sunlit" part of the surface.' When the site becomes sunlit again in several weeks, the Lunar Reconnaissance Orbiter will attempt to take pictures of the craters the probes undoubtedly made in the lunar soil."

An anonymous reader writes with an excerpt from Medical Daily about a new theory for what triggered the
"Great Dying: " "Researchers believe that they may finally know why the event occurred, but the theory is not without controversy. There are several theories, including the possibility of a meteorite hitting the planet. Previously, most researchers believed that the Permian mass extinction was a result of a series of volcanic eruptions in what is now Siberia. ... However, Daniel Rothman from the Massachusetts Institute of Technology is floating around a different theory. As he presented in a meeting for the American Geophysical Union, he believes that the mass extinction could have been caused by something much smaller. His theory is that the extinction was caused by a single strain of bacteria."

An anonymous reader writes with a blow to Facebook's policy banning accounts under pseudonyms. From the article: "A German privacy regulator ordered Facebook to stop enforcing its real name policy because it violates a German law that gives users the right to use nicknames online. 'We believe the orders are without merit, a waste of German taxpayers' money and we will fight it vigorously,' a Facebook spokeswoman said in an emailed statement."

MojoKid writes "AMD has just released some preliminary information regarding the company's upcoming Radeon HD 8000M series of mobile GPUs. Based on the naming convention alone, it may obvious that the Radeon HD 8000M series is AMD's second generation of products featuring the GCN (Graphics Core Next) architecture, which debuted in the Radeon HD 7000 series. Like its predecessors, the Radeon HD 8000M series targets gamers with full DirectX 11.1 support and improved gaming performance over the previous-gen, but the architecture also lends itself to GPU compute applications as well. The Radeon HD 8500M sports 384 Stream Processors with an Engine Clock up to 650MHz. Memory clocks will vary based on the use of GDDR3 or GDDR5 memory. The Radeon HD 8600M is essentially the same, but with a slightly higher Engine Clock up to 775MHz. The Radeon HD 8700M is also based on the same GPU, but will be clocked at up to 850MHz, for a further increase in performance over the 8600M. The Radeon HD 8800M series, however, is based on a larger, more powerful chip and will sport 640 Stream Processors with an engine clock of up to 700MHz. GDDR5 memory will be used exclusively with 8800M, at speeds up to 1125MHz. It will be interesting to see how these new GPUs stack up versus NVIDIA's latest GeForce 600M series of mobile chips."

davecb writes "Rick Falkvinge reports today that the Swedish Pirate Party has laid charges
against at least Visa, MasterCard, and PayPal before the Finansinspektionen for refusing to pass on money owed to WikiLeaks. The overseer of bank licenses notes (in translation) that 'The law states, that if there aren't legal grounds to deny a payment service, then it must be processed.'"

DECula writes "In a move not communicated to its users beforehand, Google's Gmail servers were reconfigured to not connect to remote pop3 servers that have self-signed certificates, leaving folks with unencrypted connections, or no service when getting email from other services. Not good for the small folks. One suggestion was to allow placing the public keys on Google's side in the user configuration. That would be a heck of a lot better than just dropping users into never never land."
Apparently, "valid" now means "paid someone Google approves to sign the certificate." It's not like commercial CAs have the best security track record either.

New submitter mihai.todor85 writes "It looks like Andrew 'bunnie' Huang has been quite busy lately, developing a nice open hardware laptop. He was even kind enough to provide all the schematics without NDA. For anybody interested in owning such a device, he says that he 'might be convinced to try a Kickstarter campaign in several months, once the design is stable and tested' if enough people are interested."

coondoggie writes "Insidious unknown planets lurking behind the sun ready to slam into Earth, supernova set to engulf the planet and giant, unseen asteroids screaming toward our globe are all theories espoused across the Internet as to how we will meet our demise on 12/21/2012. Do any of these theories even remotely hold out a scintilla of evidence they could happen? Not even remotely if you look at the material NASA has put out which pretty much debunks any and all of the notions being floated in across the cybersphere."
